永磁直线同步电动机的模型参考逆方法控制
The Control of Model Reference and Inverse Method for Permanent Magnet Linear Synchronous Motor
-
摘要: 由于永磁直线同步电动机结构方面的特殊性,存在边端效应、铁心开断、初级绕组分布不对称等,具有很强的耦合性。文章对此提出采用模型参考逆方法控制方案,该控制方案兼有模型自适应控制及逆系统控制等方案的特点,且具有很强的抗干扰能力。仿真结果表明,在达到同一性能要求下,该控制方案简单,更具实用性。Abstract: As permanent magnet linear synchronous motor isn’t periodic in structure,the primary iron core and windings are disconnected,its three-phase windings are actually uneven and have peculiar end effect,etc.,it has strong coupling.In this paper,the model reference and inverse method which has the advantage of model self-adapted control and inverse system control and has strong anti-disturbance function was presented.The simulation showed that this method is simple and practical in the same request of capability.
